Systems and methods of storing DNS data associated with a telephone number are presented. These systems and methods can reduce storage space needs, increase access speed and/or result in other benefits, in comparison with the prior art. In some embodiments, DNS data is indexed using a numerical representation of a telephone number rather than an alphanumeric representation. In some embodiments, DNS data associated with several different telephone numbers are grouped together within a single DNS data record and indexed using a secondary key. In some embodiments, DNS data is compressed.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A system comprising: a DNS database including a plurality of database records each including a primary key including a first portion of a telephone number and configured to identify a different particular member of the plurality of database records, a at least one member of the plurality of database records including a plurality of secondary keys each including a second portion of a telephone number and configured to index different DNS data within the member of the plurality of database records, each of the different DNS data being related to a different telephone number that corresponds to the combination of the primary key and a secondary key; server logic configured to receive a request for DNS data, the request including a representation of a telephone number; and query logic configured to identify the member of the plurality of database records including the plurality of secondary keys using a first part of the telephone number and to identify a member of the different DNS data using a second part of the telephone number.
2. The system of claim 1 , wherein the different DNS data include NAPTR data.
3. The system of claim 1 , wherein the primary key is stored as a numeric value.
4. The system of claim 3 , wherein the server logic is further configured to convert the representation of a telephone number to a numeric value for comparison with the primary keys.
5. The system of claim 1 , wherein each of the different DNS data being related to a different telephone number comprises ten or more separate DNS data each associated with a different one of ten or more telephone numbers.
6. The system of claim 1 , wherein the different DNS data share storage overhead associated with the member of the plurality of database records including the plurality of secondary keys.
7. The system of claim 1 , wherein each of the plurality of secondary keys require less storage space than the primary key.
8. The system of claim 1 , wherein the different DNS data are stored in the DNS database as compressed data, and the server logic is further configured to decompress the DNS data.
9. The system of claim 8 , wherein the primary key is stored in a non-compressed form.
10. The system of claim 8 , wherein the plurality of secondary keys are stored in a numeric value.
11. The system of claim 1 , wherein the server logic is further configured to decompress the different DNS data or the plurality of secondary keys when the different DNS data or the plurality of secondary keys are compressed.
12. The system of claim 11 , wherein the different DNS data share data compression overhead.
